Investigator Lopez has found a hoodie covered in blood at a crime scene. What would be the best way for Investigator Lopez to store this evidence so that the DNA is preserved?
In an airtight Ziplock bag
In a sealed box in her car's backseat
Wrapped in a paper bag and stored in a warm location
Wrapped in a paper bag and placed in a cool location

Wrapped in a paper bag stored in a cool location

Explanation:

If you wrap it in a ziplock bag the moisture from the blood will most likely cause it to mold.

a sealed box in a cars backseat will eventually get very warm and will cause mold.

a paper bag was a good choice but the warm location was not.

so the final answer would be a paper bag stored in a cool location.

(also thats what they do for other blood samples; store them in a cool location)
